I know that software is not free to build, so I don’t expect it’s free to use. If you want to keep the product free, you can always add a Donate me button, to let people show their appreciation.

Kudos to you for letting us know what is the way you expect to make money. I try to never use software or services where the “making money” part is not clear.

I wouldn’t probably pay for a service, but I might be happy to pay a one time fee for a function that dumps the todo file (I understand it’s a csv) every time there is an update so I can integrate that on some other workflow (like committing to git, or importing into obsidian).

Another thing I might pay for is a iPhone app so I can mark todos completed on the go, but it’s probably very difficult to to a always on window there.
